Answer:
x = 18.7
Step-by-step explanation:
Gerald's answer is almost correct.
He just needs to switch the 14 and the x.
it should be
24/x = 18/14
solve for x by cross multiplication
18x = (24)(14)
18x = 336
x = 18.7

Answer:
I have corrected the DB value calculation.
Two students, Alice and Bob, forgot to put their names on their exam papers. The professor knows that Alice does well with probability 0.8, and Bob does well with probability 0.4, independently of each other. What is the probability that exactly one of Alice and Bob does well on the exam
Answer:
[tex]Probability = 0.56[/tex]
Step-by-step explanation:
Represent the probability that Alice does well with P(A), the probability that Bob does well with P(B).
So, we have:
[tex]P(A) = 0.8[/tex]
[tex]P(B) = 0.4[/tex]
Required
Determine the probability that only one of them do well
This event is represented as: (A and B') or (B and A')
Where B' means Bob does not perform well and A' means Alice does not perform well.
And:
[tex]P(B') = 1 - P(B)[/tex]
[tex]P(A') = 1 - P(A)[/tex]
So, the probability becomes:
[tex]Probability = P(A\ and\ B')\ or\ P(B\ and\ A')[/tex]
[tex]Probability = P(A) * P(B')\ +\ P(B)*P(A')[/tex]
[tex]Probability = P(A) * (1-P(B)) +\ P(B)*(1-P(A))[/tex]
[tex]Probability = 0.8 * (1-0.4) +\ 0.4*(1-0.8)[/tex]
[tex]Probability = 0.8 * 0.6 +\ 0.4*0.2[/tex]
[tex]Probability = 0.48 + 0.08[/tex]
[tex]Probability = 0.56[/tex]
Hence, the required probability is 0.56
what is 7/8 x 4/7 in simplest form?
The expression (7/8) x (4/7) simplified to its simplest form is 1/2.
To simplify the expression (7/8) x (4/7), you can multiply the numerators together and the denominators together, and then simplify the resulting fraction if possible.
(7/8) x (4/7)
= (7 x 4) / (8 x 7)
= 28 / 56
To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 28:
28 / 56
= (28 ÷ 28) / (56 ÷ 28)
= 1 / 2
Therefore, (7/8) x (4/7) simplified to its simplest form is 1/2.

For positive integer n, the factorial notation n! represents the product of the integers from n to 1. (For example, 6! = 6*5*4*3*2*1.) What value of n satisfies the following equation?
5! X 9! = 12! x N
Answer:
The value of N that satisfies the equation is [tex]\frac{1}{11}[/tex]
Step-by-step explanation:
First we open the factorial of 12, to simplify the expression:
12! = 12*11*10*9!
So
5!*9! = 12!*N
5!*9! = 12*11*10*9!N
12*11*10N = 5!
Now we open the factorial of 5. So
12*11*10*N = 5*4*3*2*1
Since 5*2 = 10, 4*3 = 12, we have that:
12*11*10*N = 10*12*1
Now, simplifying by 10*12
11N = 1
[tex]N = \frac{1}{11}[/tex]
This is the value of N that satisfies the equation

18. Jackie drives 160 miles from Gary, Indiana to
Indianapolis, Indiana in 4.5 hours. At that rate,
how long would it take her to drive from Gary to
Detroit, Michigan, which is a distance of 240
miles?
Answer:
11 hours and 15 minutes (11.25)
Step-by-step explanation:
make a ratio
160:4.5
240/160=1.5
so 1 and 1/2 intervals of 4.5 hours
4.5+4.5= 9
4.5/2=2.25
9+2.25=11.25
The solution is 3.75 hours
The time taken by Jackie to drive a distance of 240 miles is given by the equation A = 3.75 hours
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the equation be represented as A
Now , the value of A is
Jackie drives 160 miles from Gary, Indiana to Indianapolis, Indiana in 2.5 hours
Distance = 160 miles
Time = 2.5 hours
So , the speed = distance / time
Substituting the values in the equation , we get
Speed = 160 / 2.5
Speed = 64 miles / hour
Now , the new distance = 240 miles
So , the Time required = Distance / Speed
Substituting the values in the equation , we get
Time required A = 240 / 64
Time required A = 3.75 hours
Therefore , the value of A is 3.75 hours
Hence , the time taken with a speed of 64 mph is 3.75 hours

A wooded piece of land is 68 3/4 acres. If 4/5 of this land is cleared for development, how many acres of wooded land will remain?
Answer:
13.75 or 13 3/4 acres
Step-by-step explanation:
68.75*0.2 = 13.75
The number of acres that wooden land remains is 13.75 acres.
Given that,
The wooded piece of land is 68 3 ÷ 4 acres i.e. 68.75 acres.The fourth-fifth of the land is cleared i.e. 0.80.So, the remaining should be 0.20Therefore the number of acres that wooden land remains is
= 68.75 acres × 0.20
= 13.75 acres.
Therefore we can conclude that The number of acres that wooden land remains is 13.75 acres.

Step-by-step explanation:
Answer: 1.Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2.Use the exponent rule to remove grouping if the terms are containing exponents.
3.Combine the like terms by addition or subtraction.
4. Combine the constants
Step-by-step explanation:
[tex]8(5w+7) + 9 ( 4w- 7)[/tex]
The first thing we do is distribute
[tex]8(5w+7)& 9(4w-7)[/tex]
We distribute what is outside the parenthesis to everything that is inside the parenthesis
so for 8(5w+7) we do [tex]8x5w = 40w[/tex] and [tex]8x7 = 56[/tex]
so for 9 So 9(4w−7) turns into 36w+63
so now we have 40w+56+36w+−63
now combine like terms
(40w+36w)+(56+−63)=?
